Two new functionalized diacidic ionic liquids (FDAILs) including hydroxyl functionalized diacidic ionic liquid (HFDAIL) and sulfonated diacidic ionic liquid (SFDAIL) were synthesized and characterized by 1HNMR, 13CNMR and FT-IR. The catalytic activities of these FDAILs were examined in esterification reaction of anhydrides with some alcohols to give corresponding dialkyl plasticizers under solvent-free conditions. The results indicate that HFDAIL, as hydroxyl-bearing catalyst, show better catalytic performance. Under the optimum conditions, using HFDAIL, the conversion of phthalic anhydride was high and diester plasticizers were obtained with good to excellent yields in the presence of only 10?mol% of ionic liquid. All the produced diesters could be easily recovered due to their immiscibility with the ionic liquid. Recycling experiments suggests that these ionic liquids can be reused several times without remarkable loss in their catalytic activity.

Paragraph 0041; 0052, (2015/04/22)
The invention relates both to processes for the production of functionalised materials containing alkyl sulfonic acids groups and their use as heterogeneous catalysts. The invention also relates to precursors of these new products and new organopolysiloxane sulfonic acids.
Chemistry in Water - Part VI. Catalytic Isomerization and Stereochemistry of Reduction of Acetylenics Mediated by Water-Soluble Phosphines

Reaction of water-soluble phosphines with disubstituted electrodeficient alkynes in H2O (D2O) gives rise either to mixtures of cis and trans (dideuterated) olefins or specifically to trans (dideuterated) olefins, by simple control of the phosphine amount.A cis-trans olefin isomerization catalyzed by sulfonated phosphines occurs in water and allows the obtention of specifically trans disubstituted alkenes from the corresponding cis isomers.
